Gauge readings
Actual pressure numbers, not just pass or fail
A backflow preventer is the device that stops water from reversing into the clean supply, and Georgia law requires it to be tested at installation, repair or relocation, and at least annually, by a Georgia-certified tester under EPD Rule 391-3-5-.13. SoCo Plumbers tests, repairs and files reports for Conyers assemblies, and confirms tester certification status on the call, because that status has not been supplied for publication here. SoCo Plumbers is open Monday to Friday, 9 AM to 5 PM, and closed Saturday and Sunday. If you call outside those hours, call again during business hours.
A backflow visit is a test, a record and a filing. Repair is a separate decision that follows only when the device actually fails, and it is priced in writing before it starts.


Home backflow devices most often sit on irrigation lines, boiler feeds and pool fills. Rockdale Water Resources confirms annual testing for commercial, industrial and institutional customers; residential protection is governed by the plumbing code and the EPD annual-testing rule, and we explain that distinction rather than overstating what the county tracks.
Fire lines, kitchen equipment and multi-unit properties are the commercial assemblies that most often carry a filing deadline. We schedule the test, coordinate with alarm monitoring where a fire line is involved, and file the paperwork.
Backflow is water flowing backwards: irrigation water, boiler water or fire-line water reversing into the drinking supply when pressure changes. A backflow preventer stops that reversal with internal check valves and, on a reduced-pressure zone, a relief valve that discharges if a check fails. Those internal parts wear, springs weaken and seats erode, so a device that passed last year can fail this year, and the only way to know is to test it with a differential gauge. Georgia's rule, EPD Rule 391-3-5-.13, requires testing at installation, repair or relocation, and at least annually, by a Georgia-certified tester. Rockdale Water Resources confirms annual testing for commercial, industrial and institutional customers, and we state that confirmed scope exactly, rather than claiming the county tracks every residential device in the same way.
That precision matters for the one claim this page deliberately does not make. SoCo Plumbers has not supplied backflow tester certification details for publication, so this page does not claim that certification is held. Instead, certification status is confirmed on the call before booking, and the test is performed and signed only as that confirmed status allows. For general guidance on hiring, see our guide on what Conyers homeowners should check before hiring a plumber, and for the plumbing work that often surrounds a backflow device, plumbing repairs are the related service to read first.
A backflow device is only as good as its last gauge reading, and the reading is what gets filed.
Confirm certification, test, report. Repair only follows a proven failure, and only at a written price.

The primary test instrument, connected to the test ports to measure pressure differential across each check and the relief valve against code thresholds.

Capped, painted or broken test ports are restored before testing, because a device whose ports cannot be read cannot be tested at all.

Kits matched to the assembly make, model and size, so a failed check or relief valve can be rebuilt in the same visit where the kit is available.

Make, model, size and serial number recorded for every device, so the report matches the assembly and next year's kit is known in advance.

A visual and physical check for drips, corrosion and freeze damage around the assembly, because a test result means little if the body itself is failing.

For fire-line assemblies, monitoring is notified before testing so the test does not trip an alarm, and the coordination is arranged in advance.

Test forms completed, signed as certification allows, and filed with Rockdale Water Resources or the property manager, with a copy left with you.

Testing follows EPD Rule 391-3-5-.13 and the 2024 International Plumbing Code with Georgia Amendments, effective 1 January 2026.
We test the fire-line or domestic assembly, file the report, and note the next due date. If the device fails, we rebuild and retest at a written price, so the report on file is a passing one.
We test the irrigation assembly, repair it if it fails, and file the report. Spring charge-up is the natural moment for this test, and it is when overdue devices are most often discovered.
We replace or rebuild the kitchen assembly where needed, retest it, and file the report so the inspector has a dated record. Shutoff valves and supply lines are checked while we are there.
We locate every assembly on the property, test each one, and file reports for all of them, building a simple schedule so nothing lapses again.
Conyers sits in Rockdale County, and Rockdale Water Resources is the relevant water authority across both City and County addresses, because water service here is county-wide. The confirmed county statement covers annual testing for commercial, industrial and institutional customers; residential devices are governed by the code and the EPD rule, and this page keeps that distinction visible rather than blurring it. Climate matters too: summer irrigation demand wears check seats, and winter freezes crack exposed brass bodies and split relief valves.
A commercial building's reduced-pressure zone failed its annual test, the relief valve was weeping, and a shutoff notice had already arrived.
The assembly was rebuilt with a new check seat and relief valve, retested, and a passing report was filed. The gauge readings were back inside the code threshold and the water service stayed live.
A weeping relief valve means the second check is passing water it should hold. That device will fail any test until it is rebuilt.
A homeowner's irrigation backflow device was buried under mulch and soil, could not be tested, and the report was overdue.
The assembly was excavated, raised to grade and set in a proper valve box. It passed testing and the report was filed, so the sprinkler system could run with a current record.
Keep the valve box clear of mulch and check the device for drips each spring before charging the system.
A restaurant kitchen assembly had no current certification and the device was an obsolete model with no available rebuild kit.
The assembly was replaced with a current reduced-pressure zone, retested, and the report was filed before re-inspection, with shutoff valves checked at the same time.
When no rebuild kit exists, replacement is the answer. A report cannot be filed on a device that cannot be made to pass.
Backflow trouble usually announces itself with paper, not water: a notice, a failed inspection, or a report that never arrived. Here is how each announcement is answered.

Call with the notice and we schedule the test, run the gauge, and file the report. If the device fails, we repair and retest at a written price. An assembly with a lapsed report can leave a business or home without water until a passing report is filed.

We rebuild the assembly with the correct kit, replace check seats and relief valve, and retest. If the body is cracked or the device is obsolete, we quote a replacement instead of rebuilding what cannot pass.

We locate the assembly, explain the access work needed, and raise the device to grade or fit a proper valve box where agreed, then test and file the report.

We coordinate with the alarm company before touching the test ports, schedule the test window, and notify monitoring, so the system does not trip and no false alarm is dispatched.
An assembly with an expired test can lead to water service termination. Testing before the due date, and filing a passing report, keeps the line live.
A failed device can pull irrigation water, boiler chemicals or fire-line water back into the supply you drink and cook with. Testing catches a worn check before that happens.
When a device fails, the repair or replacement is priced in writing before work starts, and the retest is included in the job, not left as a second visit.
Property managers and business owners receive gauge readings, assembly identification and a filed report that satisfies most insurance and municipal audit requests.
Records from the visit, written so you can keep and share them.

Protection from a backflow device depends on testing, because the parts that fail sit inside the body where no eye can check them.
The test ports are how internal checks are read. If ports are capped, painted over or broken, the device cannot be tested until they are restored.
A device that passed last year can fail this year as springs weaken and seats wear. That is normal, and a rebuild kit usually fixes it where the body is sound.
The report is tied to the assembly serial number, not to the property owner. Replace the device and a new test is required for the new assembly.

No firm price is published on this page. Call for a written price before work starts; any price discussion on this page is Oct-2026 Atlanta market data, not SoCo Plumbers' prices. The final price depends on assembly type, size and access, and on whether repair or replacement is needed after a failure, so it is given in writing before work, not over the phone.
Under EPD Rule 391-3-5-.13, testing is required at installation, repair or relocation, and at least annually. Rockdale Water Resources confirms annual testing for commercial, industrial and institutional customers, and the same annual cycle is the prudent schedule for other assemblies.
Only a tester holding Georgia backflow prevention certification can run the gauge and sign the report. SoCo Plumbers has not supplied certification details for publication on this page, so certification status is confirmed on the call before booking, and the test is signed only as that confirmed status allows.
It is a pressure test on the assembly that stops water from reversing into the clean supply. We connect a differential gauge to the test ports, measure the check valves and relief valve against code thresholds, and file a report with the readings.
